MUFFLER FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Apr. 16, 1912.

To all whom it may concern:

Be it known that I, MARIS SnLosnnRc, a subject of the Empire of Russia, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Mufilers for Automobiles, of which the following is a specification.

This invention is intended to serve as a means for mufiling or deadening the sound of the exhaust from automobiles and other motor vehicles.

The invention is fully set forth in the subjoined description and will be clearly understood from such description when considered in connection with the. drawing accompanying the same.

In such drawing, Figure 1 is an elevation of the invention. Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is an end view of the escape nozzle.

In said drawing 5 represents the exhaust pipe of the engine of an automobile or motor cycle, and my improved mufiler is mounted upon it as seen.

The mufiier consists oftwo hollow cones 6 and 7 secured together at their bases, by overlapping the metal of one on to a flange of the other. Between the cones and secured in the joint between them, a division plate 8 is inserted. This plate divides the cones into separate chambers, in each-of which the exhaust is deprived of some portion of its noise, and such chambers communicate with each other through a series of holes 9 formed in the plate 8 near its outer periphery, as seen at Fig. 3. The exhaust enters the cone 6 first, and having then considerable force projects itself directly against the central portion of the division plate. From the division plate, it rebounds, and having thus been deprived of the major part of its power, it then falls into the current leading to the to confine any noise within the mufiier' and prevent its escape to the outer air, and also to further take from the exhaust any remainder which may exist in it of its original propelling power. The nozzle is affixed to the small end of the cone 7, and the like end of cone 6 is attached to the exhaust pipe.

The device is very simple, but is exceedingly effective, and renders the engine almost entirely noiseless.

I claim 1. The muffler for automobiles and other self propelling vehicles, provided with a hoL low cone the small end of which is joined to the exhaust pipe of the vehicle, and the large end of which is closed by a fiat plate having its openings for the escape of the exhaust located. near the periphery of the plate.

2. The mufiler for automobiles and other self propelling vehicles, consisting of a pair of hollow cones secured together at their bases and separated by a divisional plate having the only communicating openings between the cones located near its periphery,

one of said cones being joined at its small end to the exhaust pipe of the engine, and the other cone being connected at its small end to the escape nozzle.
